This patch modifies cy8ctmg110_touch_pos to map all of the data provided
from the hardware into the cy8ctmg110 data structure for use within the
driver. In doing so, the patch also cleans up some endian conversions to
use be16_to_cpup()
This gets the driver one step closer to being able to support multi-touch.

Why just 2? What's wrong with 4? Or 8? Or some other number?
The hardware only supports tracking of 2 contact points.
Thanks,
James
